To all whom it may concern .Be it kno'wnthat I, GEORGE C. CLARK, acitizen of; the United States, residing at Mishawaka, in thebounty ofSat-Joseph and State of Indiana, havelinvented certain new and usefulImprovements in Molding Ap paratus, of which thefollowingis aspecification.

r Theinventionr'elates to an improvement tofore ordinarily practisedthere is providedin molding" apparatus of the type designed molding ofhollow metal articles:

'ln'the molding of hollow. articles as herea 'mold'formed from a patternto shape the exterior 'ofthe article, there being used withthe mold acore suitably and separately molded and designed to be arranged withincomplete the article.

type of molding particularly'where it is of l the mold so asto provide amoldingjspac'e about the corewithin the mold outline to It is essentialin this importance that the wall of the finished article be'of uniformthickness throughout, that the core be absolutely centered with respectto the mold and that it be maintained in such .position during themolding operation against possibility of accidental movement.

As heretofore practised, particularly in the molding of lasts with whichthe present invention is generally concerned, to support the-corefromanumber of arbors or similar supporting members, in order to insurea fixed relation of the core within .the mold,

the exact position of the core within the mold has been largelydetermined by the skill and practice of. the operator, with the resultthat considerable difliculty is experienced in insuring a uniformwallarticle and a very considerable period of time and unusual amount oflabor made necessary in even the few possible adjustments incidentftosuch practice.

The present invention is designed .with a view to overcoming all of thedifficulties of the present practice, particularly in last moldinginproviding a member, which may be termed a carrier for the core, whichcarrier is adapted initially for cooperation with mechanismto permit ofthe adjustment of the core with relation to the carrier, the carrier andconnected core'being then trans- ,ferred a unit to' the mold, theconstruction of the carrier and mold-being such as to cause .a specificcooperation to'insure an accurate and proper position of the core with-.in the mold.

. larly to The invention also contemplates the pro Patented Jam-12, IBM?Application filed'Dec ember 2, 1915. Serial No. 64,770.

vision of mechanism, preferably in the form of a concretemachine, withwhich the car-. rier may be readily and simply associated,

' and in which machine the core may be readily and quickly formed andsecured to and in desired adjusted relation withthe carrier, themechanical details providing particularLyfor effective, simple andexceedingly accurate adjustments to position the core with respect to'the carrier, to insure an absolutely uniformspacing' of the core fromthe moldwall when the parts are cooperated for molding.

The utilizat1on of a carrier, which as before stated constitutes themain essential of the invention with the mold, with said carrier andmold accurately formed so that theposition of the carrier on the mold'isabsolutely accurate and the same in all applicati'ons-oi the carrier,permits the use of a single arbor or support between the carrier andcore, the carrier acting in a measure "as a counterbalance to the weightof the core, and the use of a single arbor avoiding the usual number ofopenings in the finished article which have to be plugged, and hence inthis particular avoiding a loss of time and labor.

Generically stated therefore the invention contemplates the use of acore carrier adapted to beasso'ciated with a molding machine and a mold,the position of the carrier in each association being-the same under allmolding repetitions, the molding machine providing for the molding-ofthe core, and permitting the adjustment of the core box in which thecore is molded, so that the whereby the maximum of ,efiici'ency in themolding of hollow articles having uniform wall thickness, together withthe minimum of time and labor for'such operation, is a direct result.

The invention in the preferred form of details .will be described in thefollowing specification, reference being had particu- .the accompanyingdrawings, in

Fig..'11 is a broken front elevation of one i i I i Wardly for acomparatively short distance;

from the upper ends of the uprights 2 and 3, respectively. Removablysecured "upon the base is a. pedestal 6, which latterextends upwardlyabove the base 1' for a convenient distance. The pedestal 6' isdesigned'to sup;

port the table and the various adjusting mechanisms therefor. Thepedestal presents a flat bearing plate 7, extending vertically from thebase and centrally formed in the upper portion with a;verticallyextending bears against the relatively outer edges of entvertical movement, in an extension 24- from the plate 7 of the pedestal6, the upper end of the rod 23 having threaded connection at 25 with anappropriate opening in the block 18, the lower end of the rod having asuitable operating handle 26.

W The platform 10 is supported for-what might be termed pivotal movementwith relation to the supporting "member 15, through the medium of a rod27, passing rotatably through the block 18, and extension' 17of'thesupporting member and terminally threaded inwardly of thesupporting inem-- her, as at 2 8,to engage a threaded opening in theplatform. The outer end of the rod 27 is provided with an operatinghandle 29:

ing member is a bracket 30, in which, mounted for free rotatlon but heldagainst independent longitudinal movement, is an adjusting rod 31, thelower end of which is provided with an operating handle 32, and theupper end arranged for threaded connection, at 33, with the platform 10.The clamping rod 27 is arranged-about centrally of the length of'theplatform, while the adjusting rod 31is disposed adjacent one endthereof, so that the platform may be said to be centrally supported forpivotal move ment, and such movement controlled at one Guide plates 34are arranged in spaced relation to and carried by the block 18, the

inner or forward ends of the guide plates being arranged in openings 35formed in the bearing plate 7 of the pedestal. A top plate 36 is securedupon the block 18, overlying desired extent; that through the use ofthe, clamping member 20, and adjusting memthe extension 17 of thesupporting member, and the webs 9, whereby to limit the downwardadjustment of the parts.

'From the foregoing description it is obvious that, through thedescribed use of the adjusting member-12, the table may be adjustedlongitudinally of the platform to the her 23, the table, through theplatform, may be adjusted vertically to the desired extent; and that,through the use of clamping member 27 and adjusting member 31, thetable.

may be tilted or pivotally adjusted to the a desired extent; therebyproviding for practically all necessary adjustments of the table inorderto arrange for such core box as maybe necess aryunder conditions whichwill be later explained.

The table constitutes a support for the lowerend of the core box, whichis arranged in inverted position upon the table, and further adjustmentsfor such core box are provided in means, for supporting the up per endof the core box,.and in the adjustment of such means. As illustrated thecore box 37, hereinafter more particularly de-- scribed, is invertedWhen in molding pos-i-T tion upon the table 11, and the supporting meansnow to be described are arranged for cooperation with the upper end ofsuch inverted core box. The adjusting and supporting means for the toeend ,of the core box, in the particular form illustrated, shownparticularly in Figs. 11, 12 and 13, includesa sleeve member 38 disposedat right angles to the length of the main frame, and forming theterminal of a plate 39,.

havingan undercut offset guide-way 40, to slidably embrace similarlyformed edges'41 of the upright 2 of the .main frame. The plate 39 isformed with an offset Web 42,

threaded for the reception of a threaded rod- 43, which below thethreaded portion is mounted for rotation in, but held againstlongitudinal movement with respect to, an

offset 44 on the upright 2. The lower end of the rod 43 is provided withan operating disk or wheel 45, through the use of which it is obviousthat theplate 39, and thereby the sleeve 38, may be'vertically adjustedwith respect to the base plate to the desired extent. That end of thesleeve, that is, what may be termed the inner end in accordance with theprevious description, is interiorly threaded at 46 to receive anadjusting member 47, the latter-having an enlarged end beyond the sleevefor convenience of operationl Rotatably mounted in the adjusting memberis a cylindrical holder 48, said holder extending through the member 47,

and having a head.49 arranged in a recess .50, in the enlarged operatingend of the adjusting member. By this means the holder is freelyrotatable with respect to the adjusting member, but is held againstindependent longitudinal movement therein, a plate 51 covering therecess 50 to secure the enlarged end 49 of the holder therein. Theadjusting member is of materially less length than the sleeve, and theholder extends beyond the adjusting member, being formed, within thelength of the sleeve, with a disk enlargement 52 which accurately fitsthe interior of the sleeve, the holden beyond the disk being in the formof ahollow extension 53, open at diametrically opposite points for aportion of its circumferential area, and throughout its full-length asat 54. The sleeve proper is formed with diametrically opposite openings'55, extending from the outer end inwardly, so as to cointhe hollow:extensioii. .53 of" the "holder is adapted to-be .closedgb y acap 56,and a set .SCIGW 57 extends through the' sleeve 38, and is designed'to'engage themain body. of the" of secure the latter against rotationendsof the box, as applied, with lugsSO, one of which of each. set ,isformed with a pin 81 'tose'at in an opening 82 in the other of such"set.

each section forming one longitudinal half of the box. As supported uponthetable, that is in inverted position as previously noted, the core boxis sufficiently open at opposite adjusting member, and the open end ofthe member 60 is threaded toreceiv e an adjusting member 64, in which isrotathenppe'r end, the lower endof each section having closure 79 which,when .thesec- The corebox sections are formed adjacent.-

provided with an upstanding pin 89, which extends'through aslot 90 ofelongated form and. arranged transversely of the table.

,Therespective sections of'the core box are -ton1f closure 79 "withderessions. 91 which together constitute an opening into which.

when the core box is in place on the table,

the. pin 89 enters.- Manipulation of the adjusting rod 85, willtherefore independently adjust the core box on the table in an obviousmanner.

As it frequently happens that the completed article, -particlilarly whenin the form of av last, requires additional thickened lugs at the upperend of such article, whereby to provide foradditional supports whenusing the'last for makingboots or shoes, I have provided forsuch-contingency by .pivotally mounting, between-the guide plates 3i andthe block 18, the supporting arms 92 of an operating frame, the forwardendof which arms, inwardly beyond the supporting member 15 of theadjusting mechanism, are bent laterally and terminally connected tomolding pins 93, which when theparts are in applied position, arethrough the operationof the frame forced upwardly through theplatformand table, and through the openings'84 the core box, to provide openingsin the core for lug forming purposes.-

f The above description hasbeen directed primarily to the moldingmachine, wherein the core for molding the completedarticle isconstructed, the detail description having more particular relation tothe adjusting means for the core boX, in which the core 78 is molded. Itis tobe understood'that the particular type of adjusting mechanismsdescribed in the various instances is ofparticular use in connectionwith a core box designed, for .the production of a core for moldinglasts, fand that such adjusting mechanisms are designedto' this. end,although obvio'uslmechanioal changes are con \templated in suchmechanisms in order to adapt 'suchfor the use of a core box de-. signedto mold a core, for any other distinctive article. 1

An important and salient feature of the" present invention resides in ameans, designated generally as a carrier, and demgned for cooperationwith the molding machine described, and with the drag of the two-part,flask, in which the/actual molding operation of thecompletedarticle iscarried out. This carrier is illustrated particularly in ig. 17,

from which it Will be seen that'the carrier comprises a. frame 94,involving compa ra tively a, narrow strip like member including parallelupper and lower portions 95, 96,

the former being of materially less lengththan'the latter, and aconnected portion 97, At particular points, and in this essential suchpoints may be any points selected with 1 a-v'iew to their efficiency,the frame strip is thickened or otherwise enlarged, as at 98, andsaid,points are carefully machined so as to produce an absolutelyaccurate bearing surface in strict accord with the results de- -'sired.The free end of-the upper arm 95 of the carrier frame is enlarged toform a conibined bearing and Weight 99, and in suchv enlarged portion-4there is formed a 'reeess 100-, extending at right angles to the arm'95, the clampplate 101 being arranged to overlie the recess, and to bedisposed in clamping relation thereto by set screw 102.

As will be noted from Fig. 10f the drawings, themainframe of.t'hemolding ma chine is designed to removablyiceceive-and support thecarrier, and this detail alsois' w of particular importance The pedestal6,, previous description may be termed the is formed with an offset 103,in, which is. threaded a headed bearing screwlOd ('see screw is hollowto permit the passage therek through of a loelring rod 108, on'the'outer end of which is provided an irregular shaped locking head 109, andon the inner ,end of the arm 96 presents its bearing sur face on bar '4.1 The free end of arm 95 of' pressed througlrthe medium of springs 113'pass through the respective bars, contiguous bearing sections -111,-andare formed on their forward or outer ends with-irregular shaped lockingheads 114..

As previously stated the. carrier frame is provided. at desired pointswith carefully machined bearing surfaces, and for the pur-.

pose of this particular use such surfaces are shown adjacent thequnctureof the arms96 and 97, presenting at such point a right angularly relatedbearing surface, near one end of the-arm 9? remote from the arm 96,.

and atthe free end of the arm 96.

The carrier is applied to the molding machine, so that thebearingsurfaces of the carrier will contact with the bearing pdints of ,themachine just described; that is to say,-the carrier, which in use on themachine. is inverted from the position shown in Fig.

17, presents the angular bearing points" 98,

at-the juncture of the arms 96 and 97, on the respective edges of thebearing block at the free terminal of (thebar 5, while the free thecarrier bears on the adjusting screw 101 V while the arm 97 of thecarrier bears on the adjusting screwlDat', the arm 9 7 of the car rierbeing formed withLanoffset 115 to extend around the thimble 60. It is ofcourse to be understood that the screxvs-lO-and 107 The-bearing of thecarrier with respect to the machine frame is of special 'impore tance,and aswillb'e particularly noted from F1g.' "2.of the "drawings, thatsurface of the A carrier frame which, in accordance withthe Y innersurface,-is in exact alinement with the vertical centralp'lane'of thecore 100:; as

normally positioned upon the table, which is to say that if the corewere molded with the table in absolutely normal position" the verticallongitudinal plane of such. core; would coin'cideexactly with the innersur- I face of the carrier,.that is to say, the surface of such carrieropposite the bearing sur faces thereof. The'carrier' is designed as ameans for;

supporting an arbor 116, which. for the purpose of lastmolding hereinshown,'isin the form of-a pipe like section having that end adapted tobe projected within the core curved to facilitate its supportingfunction,

that portion ofthe hollow arbor designed to rest Within .the core beingperforated as:

at 117, Fig. 24, and the' free: end ofxthearbor being'open to permit theescape of steam or the like "asis usual. The arbor is provided with asleeve *118-1oose'ly and' -slidably, encircling the same, andhaving anoperative end beveled as at 119,'for the purpose which will laterappear. Thearboi' is secured to p the carrier by positioning the same inthe recess 100 of the enlargement 99 of the car rier and clamping thearbor therein by the clamp 101.

Inconnection with the molding machine forthe formation of the core, theimproved apparatus includes the use of a two-part flask which aside fromthe essentials to be hereinafter specifically described may be ofany'usual type. This flask, generally-speaking, includes the drag 120and-the cope 121,v

each provided with the usual handles 122, and having the cooperatingpositioning means as pins and openings 123. The m'old outline 12 i isformed in the flask parts in.

any usual or preferred mannerffrom a pattern, having the externaldimensionsof the sizes desired,- and the meeting edges are formed at anappropriate point ,with 'an opening 125 for the reception of the arbor.

6 other words with thecarrier in position, the

The essential characteristic of this detail of.

the invention is the provision of the'drag vmember of the flask withoffsets 126, posi tioned and arranged to cooperate 'with the bearingpoints 98 of the carrier. The off-' sets 126, which may be termedsupporting abutments, are carefully machined and; so

positioned-that that surface'of the carrier, 4

hereinbeforereferred to as the guiding surface, or the surface in thevertical longitudinal central plane of the core box in norma'lpositi0n,, is absolutely and accurately alined with the upper surface ofthe drag when the -.carrier' is applied thereto.- In

guiding surface is in absolute alinement withth e central plane of themold recess.

-'- The"operationmaybe briefly described as folloWs: The carrier isapplied to the mahin'e frame as described, the arbor positioned so as tooccupy a properrelation to,

the interior of the core box, the table and platform being slotted topermit such POSle timing of the arbor, and the corebox ap; plied'to thetable,-suitableclamps 127 operating to hold the sections'offtlfe corebox connected. The core box is supported on the tableand by the strips58 and 75. In this position, as previously described," the verticallongitudinal central plane 5? core is exact alinement withdj -g relationto the guiding surface of. the cam;

surfaceof the carrier. "Agreensand core is then formed, by suitablyfilling and tamp ing the material-Within: the core. box, which operationis obviously performed in a speedy manner, the frame arms '92 havingbeen '70" operated if desired to project the molding pins 93 into thecore bozi the, desired dis-' tance. Inthis use the frame is held in theoperated position by a spring latch 129 secured to one'ofth'e' guideplates 34 of the I adjusting mechanism;.' After-formation of th'ecore,.the core box is re'moved, and the I core carried on the arbor and thelatter supported solely by the carrier for removal fromgthemachine A:pattern having been so used to form themold outline in the flask, thecoreis applied to'such mold,by posif tioning the'carriefwith itsbearing-points 'on the bearing points 126 of the drag.- The casting,operation isf-perfo'rmed bypouring s5 the material throughthej.:usualpour'gate. 130, and the completed article 13Qjremoved i fromthe 'mold. Previoustqlthd castingoperation, the sleeve 118is-moved'do'wn the arbor into contact with the"core, so that as thearticle is cast thereab'out said sleeve forms an opening 131-in-the-upper end of the article. After molding .th'e's'le'ev'e is dis;

lodged from the article byja series of light blows from a suitableimplement, the beveled end 119 ofthe sleeve-facilitating such.operation. The material of the, core" is broken up in the usual mannerand'the' arbor and such material removed'from' the interior of thearticle. -The article thus formed; is 1001 then divided longitudinallyor otherw ise'loy a saw or the like and the sectionsQinvesti gated todetermine where, if at any place, I

the wall of the completed article is not -un"i-' I form with the desiredthickness. Having 16 determined the points of such non-uniform--ityy-the carrier is reapplied tothe molding machine, the arbor arrangedin position thereon, and the core box reapplied for the 1 molding of asecond core. Previous to such moldingl however, through propermanipulation of anyone or more of the adjusting mechanisms, the corebox'is adjusted vwith:

ments having'been perfected the second core is molded, andthe casting--operation of the completed article proceeded-with as before described'hThe:{resultunder these circumstances'will be the'completed articlehaving anabsolutely uniform wall and h'ence a. 'I

'; Of course the e, for each, casting- Zti'on isconstructid 3 for suchparticularfbpel? 30 fihereof, and it willbe understood that n onceadjusted the core box with relaon to the guidingsurface of the carrier,all cores will be absolutely uniform in their I adjustedrelation to suchsurface, and hence no change whatever will be necessary in the apparatusfor the production .of completed articles of a particular size andshape. Any

change in the size or shape of the article itself wil'l of courserequire a newoperation involving a trial article, and subsequentadjustment of the core box, if necessary.

The essential andcharacteri stic feature of the present invention is theprovision of a carrier, having a definite fixed relation with a. moldmgmachine, and a definite fixed re lation with amolding flask, and as anessential addition the provision of means whereby thefiarrangement ofthe parts for the molding'of the core may be adjusted so that the coremay have, Within limits, any desired adjusted relation with' suchguiding surface .ofthe carrier, as may be necessary to accuratelycast=the completed article in the manner described It is of courseobvious'that the necessary adjustments of themold box will in theirmaximum'degree be compara tively slight,'and hence the provisionfor1ndependent movement of thepartsto permit such adj ustment 'iscorrespondingly slight. Another and important characteristic resultantfrom the 'use ofthe carrier, is that I am enabled to support the coretherefrom by a single member, namely,"a single arbor, as the, latterremains at all times in fixed relation to the carrier and provides anefiicientQ completed article will thus have but a single -opening, andthe usualplugging heretofore necessary in molding hollow metallic laststl zrough the use of a plurality of supporting arhors or members, isentirely avoided.

The use of the carrier having a guiding.

surface adapted for fixed position with relation to the drag, and alsowith fixed position with relation to a machine in which the core ismolded, with ,relation to which guiding surface the molding essentialsfor the core may be adjusted, constitutes mechanism cooperatingtoproduce hollow articles of uni- "H1 wall thickness in a manner efiectinga material saving o'ftboth time and labor over the present means "inusefor manufacturing 2 articles.
